PROBLEM TO BE SOLVED: To provide an imaging apparatus capable of eliminating black-level offsets between fields to obtain a beautiful image. SOLUTION: An imaging sensor 303 comprises an imaging area 31; a front OB 323 having a photoelectric conversion element structure; a rear OB 324 having no photoelectric conversion elements; and a dummy pixel 33 formed at a horizontal transmission 303H. Black-level clamping is executed, based on the output signal of the rear OB 324. A black-level signal is taken out of the front and rear OB's 323, 324 and the dummy pixel 33 each. For example, when temperature rises in the imaging sensor 303, the difference between the output signal of the rear OB 324 and that of the front OB 323 is added to an effective pixel output signal and the black level is corrected.
